Title: Method and apparatus for detecting in vitro the presence of antibodies in a liquid
IPC: G01N21/82
Filed: 1959-06-29
Abstract: 869,483. Photo-electric measuring apparatus. HELLIGE & CO. G.m.b.H., FRITZ. June 29, 1959 [June 28, 1958], No. 22198/59. Class 40(3) In a method of detecting the presence of particles in a liquid a first liquid and a second liquid are brought together as superimposed layers and a light beam is passed first through one liquid and then through the other, the light dispersed from the particles being detected by a photo-cell. In the detection of antibodies the liquids are superimposed in a glass container f, the second liquid containing a known concentration of antigen, and the first an unknown concentration of antibodies. A light beam from a source a passes through the container and through a hole h in a photo-cell i when there is no antibody present, and hence no dispersion of light by aggregates. However, when aggregates are present dispersed light falls on the sensitive annular region of the photo-cell i. The output of the photo-cell is registered on meter M and by use of a calibration curve, Fig. 2 (not shown), the concentration of antibodies may be determined. A method of deriving this curve is given. The photo-cell receives light over a solid angle indicated by the lines n and this angle may be varied by providing the cell with an adjustable diaphragm.

Title: Improvements in the colouration of textile materials
Filed: 1934-07-31
Abstract: Vat dyes, dyeing with; cellulose esters or ethers, dyeing.--Textile material made of or containing a cellulose ester or ether is coloured by impregnating it uniformly or locally with a liquid containing a free leuco compound of a vat dyestuff (cf. Specifications 341,408 and 355,363), or a salt thereof, e.g. a zinc salt (cf.  Specification 378,917), drying the material under such conditions that no substantial oxidation of the leuco compound or salt thereof takes place, and thereafter oxidizing the leuco compound or salt thereof to the parent dyestuff.  The impregnating liquid may contain a swelling agent for the cellulose ester or ether, e.g. an alcohol, ester, ketone, glycol or glycol ether, preferably one which is less volatile than water, e.g. diethylene glycol.  Such swelling agent may be used in conjunction with a non-swelling diluent, e.g. a hydrocarbon, ether or chlorinated hydrocarbon.  The drying is, preferably, only partial and may be performed in a non-oxidizing atmosphere, e.g. of nitrogen, hydrogen, carbon monoxide or carbon dioxide or in vacuo. A steaming treatment may precede or follow the drying operation and water vapour may be present in the drying atmosphere to ensure that such drying is incomplete.  The following examples are specified: (1) A cellulose acetate fabric is padded with an aqueous liquor containing the zinc salt of leuco-Ciba scarlet G, gum arabic, ethyl lactate and diethylene glycol until it retains its own weight of the liquor, heated for 15--30 minutes at 60--70 DEG  C. in an atmosphere of carbon dioxide to remove about three-quarters of the water, chromed, washed and dried.  (2) A cellulose acetate fabric is similarly padded with an aqueous liquor containing Indanthrene blue 5G, Indanthrene turquoise blue 3GK, diethylene glycol, caustic soda, gum arabic, sodium hydrosulphite and Formosul, heated for 15--30 minutes at 60--80 DEG  C. in an atmosphere of nitrogen, steamed with air-free steam, treated with a solution of sodium perborate, washed and dried.

Title: Improvements in or relating to clutch control mechanism for motor vehicles
Inventor: BLAND ALBERT NORMAN
IPC: F16D43/12
Filed: 1957-07-16
Abstract: 847,944. Controlling clutches. AUTOMOTIVE PRODUCTS CO. Ltd. July 4,1958 [July 16, 1957; Oct. 9, 1957], Nos. 22534/57 and 31589/57. Class 80 (2). A motor vehicle centrifugal clutch of the type having a release collar 21 movable in one direction to disengage the clutch irrespective of the position of the centrifugal weights 31 and in the opposite direction to permit spring pressure to effect engagement through levers 23 is actuated by a servomotor capable of selectively taking up either of two positions, in one of which the release collar is held in such a position that the clutch is engageable only by operation of the weights, while in the other position it allows the clutch to be engaged by its springs without operation of the weights. In the arrangement shown in Fig. 1, the release collar 21 is connected by links 13, 15, 17, 18 to a piston 12 in a servo-cylinder 11, member 13 passing through a sleeve 43 secured to a second piston 42 loaded by a spring 48. The pistons divide the cylinder into a compartment 37 normally communicating with atmosphere, but also, by means of a valve 38, capable of being connected to a vacuum reservoir 39, a subcompartment 45 open to atmosphere, and a second sub-compartment 44 which may be placed in communication with atmosphere or vacuum by a piston valve 56 controlled by an engine-driven governor 58. In the low-speed position shown valve 56 places the servomotor in communication with an atmospheric port 54, whereby piston 42 is forced to the left to act as a stop preventing movement of piston 12 to the right, thus holding collar 21 in a position in which weights 31 may engage the clutch. When the speed rises to a predetermined value governor 58 operates valve 56 to place sub-compartment 44 in communication with a vacuum port 53, whereby the clutch springs are able to effect engagement, pistons 12, 42 being moved to the right against spring 48. In a second embodiment, Fig. 3 (not shown), the servo change-over valve is solenoidactuated, the solenoid being in circuit with the ignition switch and being controlled by governor-actuated contacts. In this arrangement also the clutch throw-out lever may be operated manually to move it from the position in which the clutch is engaged by the springs to that for engagement by the weights. In an alternative circuit arrangement the ignition switch and two sets of contacts are arranged in parallel, one set of contacts being closed when the engine throttle valve is closed, the other set being closed by the selection of the lower gear ratios, such as first and second gears of a four-speed gear-box. Specification 847,942 is referred to.

Title: Improvements in photographic reproduction apparatus
IPC: G03B27/46
Filed: 1920-07-30
Abstract: 170,427. Kulus, M. M. July 30, 1920. [Convention date]. Printing-apparatus.-In a photographic printing-machine of the type in which one rotation of an actuating-shaft effects a complete cycle of operations, the shaft having mounted on it cams or the like which operate a presser-plate for holding an intermittently-fed strip of paper against the negative and also actuate mechanism for switching on the printing-lamps for a predetermined period, the electric circuit is closed by pneumatic means operated from the cam-shaft. In the machine shown, a paper strip 23 passes from a roll 22 between adjustable guide blocks 24 over the negative at the top of the light-chamber 10. The strip is fed by rollers 25, 26, the former of which is intermittently rotated through ratchet mechanism 35, 37 operated by the shaft 32 through a crank arm 34 and a connecting-rod 38, the latter being adjustably connected to the arm 34 in order to vary the feed. The upper roller 26 is mounted in pivoted arms 29 so as to bear on the top of the paper strip, and is connected by cross belts to the roller 25. The presser-plate 41 is pivotally attached to a lever 42, which is held in the raised position by a spring 43 and intermittently lowered by a rod 47 connected to it and to a lever 44 operated by a cam 45 on the shaft 32. The switch controlling the lamp in the light-chamber 10 is closed by means of a cam 63 on the shaft 32, which causes the lever 61 to compress a pneumatic bulb 48, thus expanding a ball 49' which forces the spring contacts 51, 52 together. An adjustable needle valve with a dial 55 and indicator 60, Fig. 1, controls the escape of air so that the switch opens after a predetermined period. As shown in Fig. 1, an enlarging- apparatus may be combined with the machine, comprising a lens frame 11 connected by bellows 12 with an upper frame 13 and by belows 14 with a negative-holder 15 and light-chamber 16 below. The lens frame 11 and light-chamber 16 are adjustable in relative positions to vary the degree of enlargement.
